Why you should attend

Our training helps your team deliver accessible and inclusive products and services first time, every time, by embedding best practice in your processes and offering valuable insights to every member of your teams.

We'll show you some of the most common reasons that an app or website will fail the standard accessibility tests, and we'll also show you how to avoid them. Accessible development is a broad subject and this course will focus on JavaScript and common accessibility issues, considerations when developing modals, CSS accessibility and WCAG 2.1.

By thinking about accessibility and inclusion from the start you can prevent costly fixes at the end of a project, and also improve the user experience for everyone, not just your disabled customers.

Who is this training for

This course is primarily aimed at front-end developers, but may also be of interest to designers and managers who wish to better understand how certain design considerations may impact the overall development.

The level of training is advanced - you will require a knowledge of accessibility standards, coding and testing techniques.

What will be covered

Attendees will learn accessibility topics including:

  • JavaScript and common accessibility issues
  • Key considerations when developing modals
  • CSS considerations
  • WCAG 2.1

At the end of this course you will know how to:

  • Use JavaScript in an accessible way, avoiding common mistakes
  • Develop an accessible modal
  • Implement CSS in a way which does not interfere with accessibility
